UGS-muse preamp GB

[Algar_emi]

Don't worry Alex. I'm about to start the assembly of my preamp, just need to clear 1-2 projects from my bench. We will start discussing the software. I have the VFD display, hence I'll need your help to make the software working correctly.

Thanks again for all this work.

Glad to know that because those are the 2 displays i want to test ....
algo finishing off a couple of projects but soldering control board will start next week.

 

[Alex_twn]

I am not worried
The DFU on the forum should work immediately with the vfd

I was wondering about the front panel with the display, does nobody have experience with machining it in aluminum and could share ideas or even a file for the CNC?

I could send you my DXF and .nc file for the front if you wish but that would need to be edited for you particular controller and/or choices, but i will not make them public....don't want to see rip-offs on ebay the following week, the project deserves all my respect.

I see PCBs i designed for FW F5Turbo all over ebay...that will not happen again.

Thanks a lot! Much appreciated!

Can anyone tell me if that display is OK to complete the build? Or is there something better?

I definitely recommend to use the display listed in the BOM (or just with a different OLED color if you don't like it blue) otherwise you may end-up with incompatible footprint mount or worse incompatible controller with character ROM making the provided firmware not working with that display.
Bottom line changing display will be at your own risk.

 

[Forane12]

Oh, thanks, I was kind of attracted by the green but no more temptations, thanks for answering so fast!

 

[Alex_twn]

Eric is right. However looking at the display you are referring to, it could work except the mechanical constraints or footprints.
The controller is the one present on the OLED of the BOM and I don't use anymore the font ROM with the new GFX lib.

 

[Forane12]

Thanks Alex,

I was just hoping to find an OLED display in green but of course I can live with the blue one. Is there a green version of the one in the BOM?

 

[Eric06]

I just checked and could not find a green version but just a yellow one.

 

[Forane12]

Can you please help with a link? Is it VFD or OLED and which one do you prefer?

 

[Alex_twn]

I think Eric talk about this one NHD-3.12-25664UMY3 NHD-3.12-25664UMY3 [89.2mm x 44.0mm] - $34.75 : Newhaven Display International, Inc., High Quality Standard and Custom OLEDs, LCDs and VFDs.

It is an OLED. Personnally I prefer the OLED given the recent significant progress I did on the GFX lib, it provides much larger area for display and can do graphics.

The VFD is very nice too but somewhat limited to text only.

...Put a green or blue/green filter on top.....and green you got.

Life expectancy of VFDs is also not that good nor segment consistency over time.

 

[Alex_twn]

Right, filter could work I guess as the blue color of the OLED is rather light blue so not too difficult to modify with a filter.
To try.

Hi all,

I want to buy kit1 and kit5 (2 additional UGS modules for buffer stage).
Alex_twn say - no more PCB's. If anyone has more PCB's - please to sell me.
I offer EUR120. I am interested in UGS Muse preamp v1.2 (with M1 & M2 sockets).

regards
Ivan

 

[gnomcat]

I find the kit1. I keep looking for kit5 (2 PCB's for UGS modules)

 

[gnomcat]

I find and kit5. Thank you !
